Harza proposes to drill 10 soil <br /> borings to help define the extent of metal and petroleum soil contamination, and extend one of the <br /> bntings down to ground water to get a water sample. <br /> Lax.my discussion of the scope of work with Mr. Dennis Laduzinsky of Harza, we agreed that the i zrouud <br /> water sample to be taken from boring f3B8 would be analyzed for lead in additioa to petroleum <br /> hydrocarbon constituents, Mr. Laduzinsky also agreed tc take a utter look at the potential need to <br /> analyze soil samples from borings H131 though HB5 for metals, and samples from borings HB8 through <br /> HB10 for petroleum constituents. He was o:the opinion that pre-6ous sail sampling had deEmed the <br /> extent of these contaminants ia these particular areas of the site. <br /> The work plan is hereby approved on condition that the above issues are addressed.
